I always have people ask me where my wife gets her PSU buttons for all of the games. She orders them from Citizen's Bank. If you live in State College, I believe you can order them at the local branch but if you are not in town you can get your own set sent to you. You get buttons for all of the games, not just home games and if PSU plays in a bowl, they send you one for the bowl game. Very nice to have, especially on an undefeated season.
All you do is send $10 per set (and your name and address) to:
Citizens Bank Button Program
525 William Penn Place 153-2837
Pittsburgh, Pa 15219
You can get multiple sets and they are fun to sport on game day, no matter where you are. I am in no way associated with Citizens Bank and the money goes to a PSU scholarship fund sponsored by Citizens Bank.
